EU-Project OPEN HOUSE Dr. Natalie Eßig (Architect, DGNB Auditor) Fraunhofer Institute for Building Physics (IBP) SB 11 Special Forum: “Core Indicators” October 23 rd 2010, Helsinki Contact: natalie.essig@ibp.fraunhofer.de
The Objective EU-Project: Seventh Framework Programme European Overview about sustainability building standards: Category Indicator Country 1 Country 2 Country 3 Global Warming Potential (GWP) Environmental Quality Risks from materials Biodiversity and depletion of habitats � Timeframe: 36 months, Febuary 2010 – January 2013 � Coordination: � Management: Acciona Infrastructuras, Spain (Daniel Hiniesto) � Technical: Fraunhofer Institute for Building Physics (IBP), Germany (Dr. Natalie Eßig) � Objective: � Development of a common transparent European building assessment approach � Bottom-up-Approach: OPEN House baseline will complement the existing ones and is based on existing standards, methodologies and assessment methods � Now new system: overview about country specific assessment methods/ actual building standards and supporting sustainability all over Europe and giving advice to existing systems
The Consortium 20 partners from 11 EU countries covering the whole construction sector
The Consortium More than 50 faces behind: junior and senior sustainability experts
OPEN HOUSE Methodology WP1: Awareness and methodology for sustainable building assessment baseline definition All Partners + External Experts WP0: Project Management OPEN HOUSE baseline WP2: Designing OPEN WP3: Selection of case HOUSE model and tools studies and mechanisms for decision making WP4: OPEN HOUSE Platform Operation WP5: OPEN HOUSE Platform Dissemination and Exploitation
OPEN HOUSE Baseline Assessment methods of the 1 st generation: � Environmental and energy-efficient approach: „Green-Building-Approach“ Assessment methods of the 2 nd generation: � $ … + + + Life-cycle-orientated approach based on sustainability pillars: „Sustainable-Building-Approach “ Source: Essig, N. 2010

Partly COUNTRY? COULD THE BENCHMARK BE SET FOR THIS INDICATOR? 1 ‐ No 0 ‐ no answer, n.a . COULD THIS INDICATOR BE APPLIED? Analyses of the applicability/feasibility of the 95 pre-selected indicators in the EU-27 countries by a questionnaire in every country – Outcome: 56 indicators

OPEN HOUSE Case Studies � 68 case studies along Europe will be deployed by actors inside and outside the OPEN HOUSE consortium � The case studies will be selected by tenders “Call for Tender” (finish: October 29 th 2011) – more information: www.openhouse-fp7.eu � Building types: new office buildings (less than 10 years) and office buildings at design stage - at least 70% office use
OPEN HOUSE Case Studies OPEN HOUSE Assessment Process Assessment workshop with project partners OH Case Study Foto documentation at the building site Collecting building documents Analyzing the building documents Further meetings (if it is necessary) Overgiving the documents to the OH review committee Review by the OH review committe (4 ‐ eyes ‐ principle) OH Certificate � „ Basic and quick sustainability assessment” – for case studies outside the consortium: gives first idea of sustainability level and proposes actions to improve the level, no stringent documentation needed, based on estimations, but must be reasonable � “Complete assessment” – for case studies inside the consortium: complete documentation needed for “OPEN HOUSE – core indicators“ and no stringent documentation for the rest of the indicators from the „OPEN HOUSE – full system“
